Next-Gen fuel combustion

Fundamentals of combustion fueled by hydrogen and ammonia 

• NH3/H2/CH4 co-combustion via lab-scale swirl burner / exhaust measurement (currently preparing FT-IR and GC) / camera and filter

• Combustion diagnostics to measure important radicals (OH, NH2, NH) from new fuels' oxidation pathway and analysis

• Splitting two effects by laminar flow reactor experiment and flow visualization* - chemical kinetics and flow characteristics

• Hanyoung (Ph.D. candidate) and Sechul are doing this work.

*Collaborated with ExTENsys Lab

Post injection of H2 and NH3 to reduce NOx formated from main combustion in ICE 

• 0D and 3D CFD simulation to find the effect of post injection of H2 and NH3 for NOx reduction inside a cylinder [1]

• Adopting chemical kinetics to comprehensively investigate the details of NOx reduction pathway by using H2* or NH3 as a reducing agent

• Hanyoung and Doyeon are doing this work.

*Collaborated with SNUAL
